To all whom it mrtycmtcern:

Be it known that we, WILLIAM M. GILBERT,

dentsof Neenah, in thecounty of Winnebago and State of Wisconsimhaveinvented anew and useful Improvement in ire or Felt -Guides ofPaper-Making Machines, of which the following is a specification.

1 Our invention relates to, mechanism for and it consists of mechanismfor producing saidresult by the revolutions of said carrying-rolls, aswill be herein described.

Figure 1 is a plan View of a small section; of each endof the wire orfelt carrying roll of apaper-making machine, the journal-bearingswhichsupport the same, and the mech anism for moving the left-hand end ofsaid roll forward or backward. 'For want of room the right-hand end ofthe roll laps over the base of the mechanism for moving the lefthand endof said roll. Fig. 2 is an elevation showing the rear sideof theroll-sections shown in'Fig. 1 and an end view of the stand upon whichthe mechanism' for moving the left-hand end of the roll forward orbackward is mounted. Fig.8 is a vertical sectionlongitudinally of itsshaft of a beveledface. pulley which enters into the construction of themechanism. Fig. 4 is afront elevation of the mechanism for moving thelefthand end of the roll forward or backward and showing also theleft-hand end of said roll. Fig. 5 is a transverse section of thejournal-boX for supporting the left-hand-journal of theroll as itappears in looking to the left of the line a a of Fig. 2. elevation of aratchet-wheel, its side-inclosin g ears,and the movable journal-boxsupport for I end of the wire and felt carryported and slides. .withears 20, which depend upon each side 85 wheel.

Fig? dis a side ing supported in the journal-box 3, which is mounted toturn horizontally in its supporting-stand 4, and the journal-shaft 2 ofthe jright-hand end being arrangedtoturn in a 5 5' like manner in itssupporting-stand 4, 5 be- ;ing a block under stand 4 for bringing the.end of the roll to a corresponding height, and .4 being bolts forsecuring the stand 4 in position. I

I 6 indicates the bed-piece of the stand 7, which stand is arranged toslide toward and from the end 2 of the roll, the stand being held inposition upon the bed-piece and guided in its sliding movement by gib s8 8, the latter gib being detachable and provided with bolts 8 foradjusting its position upon the bed -'piece. The bed-piece is providedwith ears 6, bywhich the bed-piece may be secured upon the bed-timber 1.

9 is a screw arranged across the bed-piece,

revoluble in the boss 10, which boss projects 'upward from the piece 6between collars 11 11" on the screw, the screw engaging the nut 12 andbeing provided with a crank and handle 13, by means of which the screwmay ,be turned and the stand 7 moved transversely of the paper-machine.I

The stand 7. consists of its base 14, ends 15 and 15", top piece 16,having the way 17,, upon which the journal-box stand iis arranged toslide within the groove 18, and ashelf 19,'upon which the lower end ofthe stand 4 is sup- The stand 4: is provided of the ratchet-wheel 21 inclose connection with it and join together in the rear of said The wheelis internally threaded, provided with teeth 21, and mounted upon thescrew 22, the screw being secured ina 9o fixed position in the ends ofthe stand 7, so that by turning the wheel upon the screw it is carriedalong toward one end or the other of the screw, and the supporting-stand4 is moved along upon the way 17 and shelf 19,

and the end 2 of the roll thereby moved either in or opposed to thedirection in which the wire or felt is running, said direction beingindicated in these drawings by the arrow above, Fig. at. Upon the outerend of the journal-shaft 2 a wheel 23 ismounted, it being provided withv The left-hand end of the wire or felt carryacrank-pin 24, from whichis suspended by the link the dog-holder 26, said holder being connectedat the point of the pin or screw 27 by means of the link 28 with a pin29,

which extends out from the arm 30 of the supof the shaft 2 is made toreciprocate in a nearly vertical direction.

Below the point 27 the dog-holder branches to the right, 26", and left,26, of the ratchetwheel and is provided with enlargements 31 31 and dogs32 32, which dogs are adjustably secured in said enlargements withset-screws 33, and above the point 27 the holder is curved for clearingthe crank-pin and upper end of the link 25 and is then extended upwardvertically, 26, and provided with a slot 34.

ing roll terminates at the dotted line 35, (see Figs. 1 and 2,) itsshaft being enlarged over its journal diameter, as shown by dotted lines36," so that the roll is held from endwise movement in its journal-box 3between said enlarged portion and the wheel 23, and any movement of thestand 7 transversely of the paper-machine will carry the roll with it,the right-hand-end journal-shaft being made suf-v ficiently long, asshown, for allowing the necessary endwise movement for suiting theposition of the roll to the running of the wire or felt.

Upon the left-hand end of the roll from the line 37 a band 38 of somesuitable flexible material, as leather, is secured, it projecting overthe end of the roll from the dotted line 35 to the end 38. 39 indicatesthe wire or felt in Figs. 2 and 4 over said band, they being omitted inother figures for clearness of illustration.

Supported upon the journal-box 3 by the bows 40 and mounted in suitablejournalboxes 41 within said bows is a shaft 42, having upon its innerend a beveled-face pulley 43 and upon its outer and awheel 44, having acrank-pin 45 extending out from it and entering loosely into the slot 34of the dogholder. Mounted upon the shaft 42 is a collar 46, adjustablysecured thereon by means of a set-screw 47, having one end of a coiledspring 48 secured to it, the spring being arranged around the shaft 42and its other end resting against the outside of the journalbox 3.

The pulley 43 is arranged at the end of the wire or felt carrying rollwith its top surface bearing up under the flexible band, so that theouter end of said beveled-face pulley will raise said band higher thanthe top of the roll and form an incline from the end of the roll to theouter edge of the band, along which the edge of the wire or felt willtravel whenever it is inclined to run too far outward beyond the end ofthe roll. Thewire orfelt in running up this incline is caused by it tobear upon the band and said band to bear upon the top surface of thebeveled-face pulley and cause it to oscillate in the direction in whichthe wire or felt is running. The oscillation of the pulley willoscillate the wheel 44 and throw the crank-pin 45 against the right-handside of the slot 34, and consequently swing the dog 32 into engagementwith the teeth upon the right-hand side of the ratchet-wheel, Fig. 4,turning said wheel as the dog-holder is reciprocated and moving thejournal-box 3 toward the left, and consequently changing the position ofthat end of the roll toward the left and causing the wire or felt to runtoward the end 2.

For causing the wire or felt to run toward the beveled-face pulley theaction of the spring 48 is reliedon, the spring being coiled in theproper direction for oscillating the beveledface pulley in an oppositedirection from that in which the wire or felt is running. The crank-pin45 is consequently thrown against the left-hand side of the slot 34, andthereby swings the dog 32 into engagement with the left-hand side of theratchet-wheel and turns.

it upon the screw 22, so as to move the journal-box 3 in oppositedirection from that in which the wire or felt is running, andconsequently causing said wire or felt to run toward the pulley 43.

The guide herein shown is one that is termed a left-hand guide that is,one adapted for the left-hand side of the wire or felt as it is runningfrom the observer. It can be adapted for the right-hand side by slightchanges in its construction, such as extending the slot 34 fartherupward and placing the crank-pin 45 above instead of below the center ofthe shaft '42, as shown in dotted lines in Fig. 2, coiling the spring 48in the reverse direction and arranging the lower end of said spring uponthe opposite side of the journal-box 3, as shown in dotted lines in Fig.5.

In describing this invention a beveled-face pulley 43 is named as anelement and is shown in the several figures; but it should be understoodthat a segment of a pulley 43, as is shown by heavy lines in Fig. 4, orthe entire pulley, as is shown by both heavy and dotted lines in Fig. 4,is within the scope of our invention and is included in the termbeveled-face pulley. A small section of the upper part of the pulley isall that is required for throwing the dogs into engagement with theratchet-wheel upon either side,

. butfor reasons obvious to a mechanic in their The flexible exten- ICCterrace;

over the endof the roll is preferable, the slight difference inconstruction being that in using the band the top of the small end ofthe pulley is placed below the-top of the roll the thickness of saidband, while in dispensing with it the tops of the pulley and roll shouldbe flush with each other.

a The upper end of the link is provided with a slotted aperture 49instead of a circular bore for the purpose of the engagement therewithof the crank-pin 24, so as to prevent any liability of the binding ofthe pin by reason of the action of the two links which control themovements of the holder 26.

Attached to the end 15 of the stand 7 is a flexible connection 50, whichextends to and is connected with the left-hand dog'holder for thepurpose of limiting the movement of the dog-holder and journal-box 3toward the right beyond a predetermined limit for-preventing injury toany of the parts.
